Considered as one of the greatest authorities in the world in the art of teaching Brazilian Jiu-Jitsu, Master Mansur, 9th degree black belt, presents his new DVD on the defenses against the most feared submission techniques of this style.  Just as with previous work, Mansur explains progressively, and in great detail, how to employ Jiu-Jitsu techniques to escape form these situations.  Arm-locks, chokes, leg locks, and foot locks.  For all these techniques, there are defenses in Jiu-Jitsu, which will allow you to counter attack and shift the fight to your favor.
